CMB 311 Study Guide - Endergonic Reaction, Thermodynamics, Tsuneko Okazaki
Document Summary
Thermodynamics: tells us whether a reaction will go or in what direction. Kinetics: tells us how fast a reaction will go. Gibbs free energy: g = h - ts. Gibbs free energy deals with a reaction"s ability to do work. Change in free energy of a system as rxn proceeds: g. Enthalpy reported as h refers to the heat content of a reacting system. Change in heat released or absorbed during rxn: h. Entropy reported as s refers to the randomness/disorder of a system. G < 0 the reaction is spontaneous, favorable, exergonic (energy is released) G = 0 the reaction is at equilibrium. G > 0 nonspontaneous, unfavorable, endergonic (energy is required) To favor a reaction: g (-), h (-), s (+) The value of delta g for b=>a would be -10kj/mole because the forward reaction and reverse reactions have opposite delta g values . In thermodynamics, what do spontaneous, favorable, exergonic and.
